unable to use <p:ajax> on my primeface's datatable
提问by cascadox
I'm having some problems with datatable's instant row selection, exactly <p:ajax/>. It's giving me this error:
我在数据表的即时行选择方面遇到了一些问题，正是<p:ajax/>. 它给了我这个错误：
<p:ajax> Parent not an instance of ClientBehaviorHolder:
org.primefaces.component.datatable.DataTable
So I did some research and I think it's a problem with an old version, so I've updated my version to 3.0.M3-SNAPSHOT but I have still the same error and I wonder why!
Here is my page code:
所以我做了一些研究，我认为这是旧版本的问题，所以我已经将我的版本更新为 3.0.M3-SNAPSHOT 但我仍然出现同样的错误，我想知道为什么！
这是我的页面代码：

currentProjet=currentChangerStatus.getProjets();
System.out.println("le projet est : " +currentProjet.getLibelle());
FacesContext.getCurrentInstance().getExternalContext().redirect("infoprojet.xhtml");
}
Maybe I didn't integrated the Primefaces jar correctly, so here is my POM(maven):
也许我没有正确集成 Primefaces jar，所以这是我的POM（maven）：

Don't try to put a <p:ajax>inside the the <p:dataTable>. This is one of the PrimeFaces components where you declare the Ajax-related attributes right in the component itself.
不要试图将 a<p:ajax>放入<p:dataTable>. 这是 PrimeFaces 组件之一，您可以在其中在组件本身中声明与 Ajax 相关的属性。
Here is an example from the PrimeFaces documentation:
以下是 PrimeFaces 文档中的示例：
<p:dataTable
var="car"
value="#{carBean.cars}"
selectionMode="single"
selection="#{carBean.selectedCar}"
onRowSelectUpdate="carListForm:dialogContent"
rowSelectListener="#{carBean.onCarSelect}">
...columns
</p:dataTable>
See how the rowSelectListenerattribute is declared right inside the <p:dataTable>?
看看rowSelectListener属性是如何在<p:dataTable>?
The error you were getting: Parent not an instance of ClientBehaviorHolder
你得到的错误： Parent not an instance of ClientBehaviorHolder
This means that the parent tag cannot contain an Ajax tag. The example above is from the PrimeFaces 2.2 documentation, but I believe 3.0 is similar.
这意味着父标记不能包含 Ajax 标记。上面的例子来自 PrimeFaces 2.2 文档，但我相信 3.0 是相似的。
EDIT:
编辑：
My mistake! I replied from home and didn't have access to my code that uses PrimeFaces 3.0. In PF 3.0 (unlike PF 2.2) you can embed the <p:ajax>element. Here is a code sample that works for me:
我的错！我在家里回复了，但无法访问我使用 PrimeFaces 3.0 的代码。在 PF 3.0（与 PF 2.2 不同）中，您可以嵌入<p:ajax>元素。这是一个对我有用的代码示例：
<p:dataTable
id="myDataTable"
value="#{myBean.rowObjectList}
var="rowObject"
selection="#{myBean.selectedRowObject}"
selectionMode="single">
<p:ajax
event="rowSelect"
listener="#{myBean.onRowSelect}"
update="someElement" />
<p:ajax
event="rowUnselect"
listener="#{myBean.onRowUnselect}"
update="someElement" />
</p:dataTable>
Here are my listener methods signatures:
这是我的侦听器方法签名：
public void onRowSelect(SelectEvent event) {
// your code here...
}
public void onRowUnselect(UnselectEvent event) {
// your code here...
}
I don't know enough about your webapp to understand how your redirect is meant to work, but I will also give you a code sample that I'm using in my webapp after the user clicks a Logout button and I redirect them to a "you are logged out" page. This code is called from an action method.
我对你的 webapp 了解得不够多，无法理解你的重定向是如何工作的，但我也会给你一个代码示例，在用户单击“注销”按钮并将它们重定向到“您已退出”页面。此代码是从操作方法调用的。
FacesContext ctx = FacesContext.getCurrentInstance();
ExternalContext ectx = ctx.getExternalContext();
ServletContext sc = (ServletContext) ectx.getContext();
ectx.redirect("http://somedomain.org/somepage.html");

try to keep one jar of primefaces i.e. either 2.1.1 or 3.1.1 not both, they create conflicts. it works for me for the same error hopefully your will resolved as well.
尽量保留一罐 primefaces，即 2.1.1 或 3.1.1 不是两者，它们会造成冲突。对于同样的错误，它对我有用，希望您也能解决。

Did you put editable=trueinside your datatable? Try this:
你把你的数据表放在editable=true里面了吗？尝试这个：
<p:dataTable
id="myDataTable"
value="#{myBean.rowObjectList}
var="rowObject"
selection="#{myBean.selectedRowObject}"
selectionMode="single" editable="true">
